【摘要】： 垃圾郵件又稱“不請自來的商業(yè)郵件”，給我國的生產(chǎn)或商務(wù)活動帶來了巨大的損失。雖然陸續(xù)推出幾款郵件過濾軟件，但在對比幾種郵件過濾軟件的原理后發(fā)現(xiàn)，目前的郵件過濾方法或多或少地存在著語義缺失的問題，當(dāng)垃圾郵件發(fā)展到一定程度的時候，目前的郵件過濾算法將難以應(yīng)付。 本文針對現(xiàn)有垃圾郵件過濾器在對郵件內(nèi)容進(jìn)行處理中的語義缺失問題，提出了將自然語言理解的相關(guān)方法引入郵件判斷中來，使郵件過濾器能夠從語義的高度對所收到的郵件進(jìn)行過濾和分類，以達(dá)到減輕用戶人工處理郵件的工作量的目的。另外，將概念分析理論引入到自然語言理解中來，利用概念分析理論不涉及具體語言這一特點，來解決漢語語言構(gòu)成復(fù)雜，口語化嚴(yán)重的問題，并在此基礎(chǔ)上設(shè)計了基于概念分析的郵件內(nèi)容分析方法。 通過利用廣告行業(yè)的領(lǐng)域?qū)Ｓ眯g(shù)語的特點，構(gòu)建了廣告領(lǐng)域的領(lǐng)域本體，并作為概念分析的基礎(chǔ)和知識庫。采用的技術(shù)路線主要是：首先將對漢語語言的定義和語言的實例定義到本體庫中，從而省去了數(shù)據(jù)庫層，方便了系統(tǒng)的構(gòu)建，且用可擴展標(biāo)記語言(XML)來定義本體，為以后的擴展奠定了基礎(chǔ)。用描述邏輯來支持基于概念分析的自然語言理解和推理，其次是利用描述邏輯支持分層設(shè)計的特點，設(shè)計出基于概念分析的、層次性的郵件領(lǐng)域本體。 最后，依據(jù)上述研究基礎(chǔ)或設(shè)計想法，，設(shè)計了一款基于自然語言理解和領(lǐng)域本體的郵件過濾器，并提出了一種符合真實郵件過濾環(huán)境的句法分析和語義分析算法。以廣告垃圾郵件作為測試用例進(jìn)行測試，并給出相應(yīng)的測試數(shù)據(jù)，對該算法進(jìn)行了驗證，取得了令人滿意的結(jié)果。
[Abstract]:Spam, also called "unsolicited commercial mail", has brought huge losses to the production or business activities of our country. Although several kinds of mail filtering software have been introduced one after another, after comparing the principles of several kinds of mail filtering software, it is found that the current mail filtering methods have more or less the problem of semantic lack, when spam develops to a certain extent, Current mail filtering algorithms will be difficult to cope with. In order to solve the problem of semantic deficiency of existing spam filters in the processing of email content, this paper proposes a method of natural language understanding in mail judgment. The email filter can filter and classify the received mail from the semantic level, so as to reduce the workload of the user to handle the mail manually. In addition, the conceptual analysis theory is introduced into natural language understanding to solve the complex and colloquial problems of Chinese language structure by using the feature that conceptual analysis theory does not involve specific language. On this basis, a method of mail content analysis based on conceptual analysis is designed. By using the characteristics of domain terminology in advertising industry, the domain ontology of advertising field is constructed, which serves as the basis of conceptual analysis and knowledge base. The main technical routes are as follows: firstly, the definition of Chinese language and the examples of the language are defined into the ontology library, which saves the database layer, facilitates the construction of the system, and defines the ontology with extensible markup language (XML). For the future expansion laid the foundation. Description logic is used to support natural language understanding and reasoning based on conceptual analysis. Secondly, the hierarchical mail domain ontology based on conceptual analysis is designed by using description logic to support hierarchical design. Finally, according to the above research basis or design ideas, a mail filter based on natural language understanding and domain ontology is designed, and a syntactic and semantic analysis algorithm is proposed to fit the real mail filtering environment. The algorithm is tested with spam as a test case and the corresponding test data are given. The algorithm is verified and satisfactory results are obtained.
